Cognitive restoration of reversed speech
Article Abstract:
Speech is a complicated auditory signal, requiring much processing. The intelligibility of speech has been studied and was found to be resistant to time reversal of local sectors of a spoken sentence. The results support recent speech encoding theories stating that a detailed auditory analysis of short term acoustics is not critical to the speech code, but the ultralow-frequency modulation envelopes of 3-8 Hz are significant cues to intelligibility.

Right on in sign language
Article Abstract:
Functional magnetic resonance research suggests that individuals who speak both the American Sign Language (ASL) and English use different areas of the cerebral cortex. Bilingual speak registers brain patterns which are marginally different, however. Further research is required to establish if ASL utilizes a unique area of the cerebral cortex, irrespective of other languages used at the time.

A common neural code for frequency- and amplitude-modulated sounds
Article Abstract:
A common neural code appears to encode both frequency modulation (FM) and amplitude modulation (AM) in the auditory system. The code transducts FM changes into AM changes before before binaural convergence at the brain stem. Support for this position involves the presence of a delay in the phase of FM in one ear when compared to the phase of AM present in the other ear.
